PART 1: Get Ammo From the Supply Drop & Hold the Area

The moment you approach the ammo drop, you'll be attacked by many enemies, kamikaze and tree sniper alike. They'll come from your right (the east-southeast). Be prepared to hit your Melee Attack at a moment's notice, and dash backward to cover as soon as you're able. Since you'll be highly outnumbered, you'll oft be in danger of dying -- go Prone and heal it off whenever you reach that point. Your goal is to survive.

Take note: before you move on, you can swap your default gun with something else. There are several guns near the ammo drop bag, including a Thompson, Browning M1919, and a Scoped Springfield. After you pick one up, refill your ammunition by using the bag. The rest of this mission's walkthrough will assume you have the Scoped Springfield.

PART 2: Get to Cover & Enter and Clear Out the Tunnel

Quickly refill your ammo at the bag, then run south-southwest as fast as you can, and duck into the bunker. Drop down the hole nearby, and progress westward with caution. You'll hear voices becoming increasingly louder. Stick to the left side of the tunnel, and the guards within the underground room won't notice you. Cook a grenade and throw it in to kill them with little trouble.

If you're a good shot, you can kill several foes at once with your Scoped Springfield. Since the tunnel is so narrow, chances are high that they'll line up for you, and you can then shoot a single bullet through them. Sadly, you won't be able to kill them all this way, as some won't move; if your grenade didn't get 'em, pick them off normally. Keep your Springfield and switch out your other weapon for one of their Type 100s.

With them out of the way, you're free to move forward. Climb the ladder when you reach it.

PART 3: Assault Shuri Castle

Shortly after you and your compatriots line up against the bunker, Japanese soldiers will assault you. Take cover, but be prepared to use your Melee Attack; some of your enemies will inevitably dive into your trench. Your Scoped Springfield can be fired eastward through a line of foes, killing several at once, but only use this method if you're sure its bullets won't be wasted. There's a mounted machine gunner in a red tower to the south-southeast; snipe them ASAP.

When you head eastward and are about to reach the stone steps, an enemy will emerge from the ground to your left (east-northeast). Jump to avoid his fire and be ready to Melee Attack both him and another banzai attacker. Afterward, turn your attention to the staircase to your south, climb it halfway, then crouch and start sniping soldiers from afar. When it's safe to, switch to your Type 100, run into the area alongside your fellow soldiers and continue killing (and as always, have your Melee Attack finger at the ready, or you'll regret it).

Soon thereafter, your companions will run up the stairs beneath the mounted machine gun tower. Before you join them, run around the field you'd just cleared to pick up more Type 100 ammo (and be careful, as some foes may still be hiding in the ground). Finally, join your fellows. Many Japanese soldiers will be firing at you from behind bunkers and walls. Cook some grenades to clear them out, and use your Scoped Springfield on any leftovers. Some are hiding behind the burnt-out rice paper doors, so scan the area with your scope carefully.

When you proceed westward, more enemies will emerge. There's a small hut located northwest of the water (it's the only one in the area), and inside waits another Type 100 and a Scoped Arisaka. Use up whatever Springfield bullets you have left, then grab the Scoped Arisaka and load up on bullets. From there, follow your soldiers into the nearby hallway. Along the way, you can duck into a small room at your right to collect a Browning M1919 (and more Type 100 bullets), but you should hang onto the Scoped Arisaka and Type 100 combo.

Following that, charge up the long series of stairs.

PART 4: Eliminate the Mortar Crews (4 of 4)

Run alongside your fellows until you hear gunshots. To the near south, Mortar Shells will be sitting on a crate. The Use command will enable you to pick 'em up, prep 'em, and then you can toss 'em. Enjoy laying waste to the countryside! You can explode buildings, soldiers, and more, and you should have fun, as the supply of shells is infinite.

After you've obliterated the first two crews, you can jump into their pits to pick up more Mortar Shells and continue raining down death. Make sure you have one bomb in hand when you climb up the stairs toward the south, as the third crew waits not far ahead. Eliminate them, then jump into their camp and resume throwing shells everywhere. If the mounted machine gunner tries to spoil your fun (he's in the building to your east), stop him cold with your Scoped Arisaka.

The fourth and final camp isn't far from the third. Once you've cleared it out, enter the hut directly south of it to collect another Death Card, then move toward the building to the east. Banzai attackers will emerge; gun them down quickly, then resume entering the building and moving eastward (taking another Mortar Shell with you if you want).

PART 5: Eliminate All Enemies in the Area & Regroup With the Squad

This objective is relatively self-explanatory, and -- aside from the occasional grenade threat -- shouldn't prove too difficult. There are countless spots for ducking and covering, and you should still have a fully-loaded Scoped Arisaka on you, which makes things even easier. Your Type 100 will work for close- and long-range encounters, thanks to its accuracy, and you'll be able to pick up ammo for both from the corpses. Make sure you do that before proceeding.

PART 6: Assault Shuri Castle (Tunnels)

When the shooting dies down, regroup with your squad and enter the castle. You won't get far before you're ordered to man an MG, so find that mounted machine gun and annihilate a courtyard of foes. Once you're done, switch to your Type 100 and head east. A few more soldiers will try to stop you before you reach the stairs leading downward (in the east-northeast corner of the floor). Crawl forward through the tunnels until you hear gunshots and see two red barrels. Shoot those to blow them up, and it will kill any enemies nearby; move south afterward.

Eventually, you'll enter a large, round area, filled with fires and foes. Using cover to your advantage, take them out carefully. Grenades, if you have any, will help to make short work of them -- they'll often be sitting together in groups of two or more. When they've all fallen, your only option is to head southeast. Use any red barrels you see to damage your enemies, and keep moving forward.

After dealing with a handful of foes, you'll ascend a staircase leading west.

PART 7: Secure the Supply Drop in the Courtyard & Defend the Area

Follow your Sergeant until you're told to hold your fire, then stand back. Shortly after they inspect some Japanese soldiers, a slew of them will ambush you. Find some strong, secure cover, and fight back until you're given permission to call for air strikes.

PART 8: Radio in Air Support on the North Buildings

A good place to position yourself is at the bottom of the stairs, just southeast of where your comrades were blown up. Call in air support on the north building, then go prone. Numerous banzai attackers will try to kill you, but instead of shooting, they'll just run up to you and you can Melee Attack them all.

PART 9: Radio in Air Support on the East Building

Stay in your prone position, and call in two air strikes on the east building to destroy it.
